A mild, efficient and general method for the chemospecific α-oxygenation of aldehydes is described. Treatment of a series of aldehydes with N-tert-butyl-O-benzoyl hydroxylamine hydrochloride gives the corresponding α-oxygenated carbonyl via a proposed pericyclic rearrangement process.
bulky N-substituents and non-polar solvents, and for the O-protonated form. Free energies of activation for rotation about the carbonyl-nitrogen bond were calculated in a series of formylhydroxamic acids.
